In the world ofBaldur’s Gate 3(BG3), few abilities are as iconic or satisfying as theEldritch Blast-a spell synonymous with the Warlock class. This crackling beam of arcane energy is not only visually striking but also one of the most powerful cantrips in the game when used correctly. However, what truly transforms Eldritch Blast from a basic attack into a devastating weapon is theAgonizing Blastinvocation. Together, these two mechanics create one of the most reliable sources of ranged damage inBaldur’s Gate 3, making them essential for anyone looking to master the Warlock’s potential.
Understanding Eldritch Blast in Baldur’s Gate 3
Eldritch Blast is a cantrip available exclusively to Warlocks. Unlike many other cantrips, it scales with your character’s level and can deal significant damage throughout the entire game. As a spell that doesn’t consume spell slots, it becomes the Warlock’s bread and butter attack, allowing for consistent damage output in every encounter.
The spell functions as a ranged spell attack that deals force damage-one of the most reliable damage types inBaldur’s Gate 3since very few creatures have resistance to it. Force damage bypasses most defenses, making Eldritch Blast an effective choice against nearly any enemy.
Base Mechanics of Eldritch Blast
- Spell TypeCantrip
- Range18 meters
- Damage TypeForce
- ScalingIncreases in beams with level (up to three at level 10)
- Attack RollBased on Charisma modifier
When you cast Eldritch Blast, you roll a ranged spell attack against your target’s Armor Class (AC). On a hit, you deal 1d10 force damage per beam. As you gain levels, the number of beams increases-allowing you to target multiple enemies or focus all beams on one foe for greater burst potential. This scaling makes it one of the best cantrips inBaldur’s Gate 3for long-term play.
What Is Agonizing Blast?
Agonizing Blastis one of the most popularEldritch Invocationsavailable to Warlocks. Invocations are special upgrades that modify how your abilities work, and Agonizing Blast directly enhances Eldritch Blast by adding your Charisma modifier to the damage of each beam. This means that as your Charisma increases, so does your total damage output per cast.
For example, if your Warlock has a Charisma score of 18 (+4 modifier), each beam of Eldritch Blast will deal 1d10 + 4 force damage. When you gain multiple beams, that bonus applies to every beam individually. This turns Agonizing Blast into one of the strongest damage-boosting options for any Warlock build in BG3.
How to Unlock Agonizing Blast
You can select Agonizing Blast once you reach level 2 as a Warlock. At that point, you’ll be able to choose two Eldritch Invocations, and this one should almost always be one of them. To qualify, you simply need to have the Eldritch Blast cantrip, which every Warlock begins with.
- RequirementEldritch Blast cantrip
- EffectAdd your Charisma modifier to Eldritch Blast damage rolls
- Best Level to TakeLevel 2 (as early as possible)
Most experienced players consider Agonizing Blast to be an essential pick because it scales naturally with your primary ability score-Charisma. It provides consistent value in every fight and doesn’t rely on situational conditions like other invocations.
Why Agonizing Blast Is So Powerful
The synergy between Eldritch Blast and Agonizing Blast lies in the spell’s multi-beam structure. Each beam benefits individually from your Charisma modifier, allowing your damage to scale exponentially as you level up. Here’s how it looks in practice
- Level 1-41 beam â 1d10 + CHA damage
- Level 5-92 beams â (1d10 + CHA) Ã 2
- Level 10-113 beams â (1d10 + CHA) Ã 3
- Level 12 (cap)3 beams â maximum potential damage with full Charisma scaling
This scaling ensures that your Eldritch Blast remains relevant even at higher levels, where other cantrips might start to feel underpowered. Combined with high Charisma gear, potions, or buffs, the damage potential becomes truly impressive.
